Is it possible to combine 2 web.xml with a Maven overlay

I have a web application "A" defined in a military project. I created another web application “B” that imports all the content “A” with the overlay.

The web.xml file of application "B" is the same as application "A", with the exception of additional listeners. Therefore web.xml B contains a lot of duplicate content with A.

Question: Can I tell maven-war-plugin about merging web.xml from A and B instead of replacing web.xml of file A with web.xml from B?

In your case - additional listeners - there is a simple solution. If your application is Servlet 3.0 or higher, you can register listeners B with the annotation:

@WebListener public class BListener implements ServletContextListener { public void contextInitialized(ServletContextEvent sce) { System.out.println("Started BListener"); }

If exposure B is more complex than an extra listener, you can consider a web fragment (requires Servlet 3.0)
